## Introduction
The `gitlab` Helm chart deploys just GitLab into your Kubernetes cluster, and offers extensive configuration options. This chart requires advanced knowledge of Kubernetes to successfully use. For most deployments we **strongly recommended** the [gitlab-omnibus](gitlab_omnibus.md) chart, which will replace this chart once it supports [additional configuration options](https://gitlab.com/charts/charts.gitlab.io/issues/68). Due to the difficulty in supporting upgrades to the `omnibus-gitlab` chart, migrating will require exporting data out of this instance and importing it into the new deployment.

## Cloud Native GitLab Chart
GitLab is working towards building a [cloud native GitLab chart](https://gitlab.com/charts/helm.gitlab.io/blob/master/README.md). A key part of this effort is to isolate each service into its [own Docker container and Helm chart](https://gitlab.com/gitlab-org/omnibus-gitlab/issues/2420), rather than utilizing the all-in-one container image of the [current charts](#official-gitlab-helm-charts-recommended).
